Fig. 5

Expression of dlx2a visualized using whole mount in situ hybridization. Embryos exposed to SU5402 at 2.5 μM in either DMSO (b & e) or G4TFSA (c & f) display reduced localization and expression of dlx2a compared to control (DMSO exposed only (a & d) in the hindbrain (arrow) and in the pharyngeal arches (arrow head, * lack of pharyngeal arches). The first row depicts the embryos in a later orientation, the second row depicts the embryos in a ventral orientation
